AUMÜLLER spindle drives can be used in SHEV systems and as well as for natural ventilation via automated windows, mainly in the roof areas. The window openers are installed surface mounted. The preferred installation locations are window frames (main closing edge or the side closing edge).

The application area includes outward-opening, large medium-heavy to heavyside-hung, bottom-hung, top-hung, friction hinged and parallel outward opening windows and skylights.

With the aid of external synchronisation modules, a synchronous mulit drive operation of up to 4 drives is possible.
